To all whom it may concern:

Be it known that I, CHARLES E. BaooKs, a citizen of the United States,-residing'in the city of St. Louis and State of Missouri, have inventeda new and useful Engine- Oiler, of which the following is a specifica-This invention relates toV oilers for enginesand has for an object theproduction of a device which operates automatically to lubricate theworking parts of an engine.

Another object of the 'invention is to produce a device of the charactermentioned. free from moving parts, which is operated lf by the use 'ofthe pressure and vacuum created in the crank case of the engine by thenormal operation of the pistons.

'Io these and other .ends I have designed,

combined and arranged the several parts in' the 4manner hereinaftershown and del scribed, reference being had to the accompanying drawingin which* Figure l is a vertical section through the cylinders and crankcaseof an engine in Whichuthe device of the preQent-invent-ion isembodied, Fig. 2 is an end view of an en gine showing a part of thecrank case broken away, disclosing a portion of the deviceof the presentinvention. F ig. 3 is a horizontal sectional view on the line 3-3 of F il, and F ig. 4 is a ldetailed view of one o the nozzles constituting aportion of the device of the present invention.'

In the embodiment of Arny invention-illustrated ili/the'drawing, theoiling device is shown in connection with a four cylinder engine, .theseveral cylinders thereof being indicated by A in which are operativelymounted pistons B. The several pistons B are'connected to a crank shaftC by connecting rods D, which with said crank shaft C are housed in acrank case E. The crank shaft C is mounted in bearings formed in thecrank case E in the usual manner, and the several pistons B areconnected thereto by the connecting rods D in such a manner that the twopistons to the one side will travel downwardly while the two pistons tothe other side travel upwardly and vice versa, as the vengine continuesto operate. The crank case E is provided with a removable bott-oni orcap 1 which is farranged to be joined to the upper part of the crankV-case 2, which is formed integral with the to form a tight and perfectjoint. The crank case E is divided into two chambers and Cr by thevertical partition wall 3, formed integral, with the main engine castingin the upper part of the case 2 and the continua tion partit-ion wall 4formed in the iower part of the case E. v

The oil chambers H and I are supported by the 'lower part of theremovable bottoni or cap l, from which they are separated by ahorizontal plate or wall 5. In the einbodinient shown the chambers H andL are formed integral with the lower portion of the crank case E. The`bottom of the chainbers H and I incline towards e center open# ings 6,which are provided with removable plugs 7 for draining the vsaidchambers. Each of the chambers H and I also has at its outer end anopening 8, 4which is closed by a screw plug 9, which plugs may bereopenings l1 inthe plate or wall 5 constitute intercommunicatingpassages, whereby the oil chamber H is communicated with the chamber G,and the chamber I 1s communi- `cated with the chamber F.

In the upper face of the plate or wall 5, at suitable intervals, are aplurality of threaded orifices into which are screwed: nozzlesv or. oildistributing devices l2, the upper ends of which are inclined so as todirect the oil ejected therefrom toward the s point of the mechanismthat it is desired to lubricate. Thus vin F ig. 2 the oileyected lfromthe nozzle is directed toward the wrist pin connecting the piston to theconnecting rod, as indicated by the dotted line, and as the parts lnovethey are brought into the path of the spray of oil, thus being freelyand effectively lubricated at each` reciprocat-ionof the pistons.

In practice the device operates as follows: Either one or both of thechambers II and I are filled with lubricating oil of suitable quality.As the pistons on one side of the partit-ion wall 3 4 move upwardly,those on the opposite side inove downwardly, thereby creating pressurein the chamber in which the pist-ons are moving downwardly and a partialvacuum in the other chamber in which the pistons are moving upwardly.The pressure thus created is con- Idd ias

aaa

. Bepi it al ducted to the oil chamber on the opposite side of thepartition `wall 3-4' through the passage lO-ll, thereby ejecting oilthrough the several nozzles supported above the oil chamber, withsutiicient Jforce to cause a spray or stream of oil to raise from eachto the upper portion of! the cylinders above the chamber, therebythroughly lubricating all the interior moving, parts of the engine.Tliejartial vacuum 'cieated in the upper Chamb r, by the upward movementof the pistons, reduces the pressure so that the oil may be ejected morefreely by the pressure caused by the de'p essing of the pistons in theopposite cham er. This action will be -repeat-ed als the direction oztmovement of the pistons is changed as the engine continues y tooperate', ejecting oil into one side of the engine and then into theother at each stroke of the pistons reciprocating inthe cylinders. Thesurplus oil discharged from the nozzles, and which is not taken up bythe moving parts, recedes to the bottom of the crank case and flows backinto the oil chamber on the opposite side ot the partit-ion wall 3-4. Itwill be apparent that the arrangement ot the device tends to leep thesupply of oil. in` the oil chamberstequalized, as the oil `passes fromone oil" chamber to the other,

through `the upper chamblers, untilthe level of the oil in both ot theoil chambe'is` is the same. c

The device is automatic in action, eject; ing a predetermined quantityof lubricant, depending upon the size of the opening in the nozzles, ateach stroke ot the-pistons. The device is also economical, with respect.to the amount of oil consumed, because all the surplus oil not utilizedin lubricating the parts, 4is conducted back to the oil cham!I bers.

l am aware that numerous changes in the details oi? construction may bemade without departure from the spirit and scope of my invention. I donot limit myself, theretore, to exact details of construction shown anddescribed7 but that I claim and ters-Patent is:

l. The combination with an engine casing, ota crank case attachedthereto, a partition dividing said crank case into separate chambers, aseparate oil container below cachot1 desire to secure by Letsaidchambers, a passage leading it'roiireach of said chambers to the oilcontainer below the other of said chambers, and a number of oildistributing devices located between the vertically adjacent chambersand oil containers through which oil is ejected from each of the oilcontainers into the chamber above' thesame when the engine is in operation, substantially as specified.

2. A device of the character described, comprising' a number oit oilcontainers, an

independent chamber above each of said oil containers, a wall separatingsaid chambers from said` oil containers and a number ot nozzles carriedby said wall through which oil is forced when the engine is inoperation, substantially as speciied.l v

3. ln an engine, an oil container, oil dis tributing devices leadingfrom said container to the crank case of the engine and a passage forintroducing air pressure in said oil container below said`oildistributing devices, substantially as specified. l

4. In an engine, the combination with a number of independent crankcases, of an \oil container mounted-below each of said crank cases,anumber of oil distributing de* vices between each of said' oilcontainers and the respective vertically adjacent crank case, andintercommunicating assages between the laterally adjacent crank case ofone unit and vthe container of the adjacent unitT substantially asspecied.

yInl an "engine, the combination with a 'crank caserthetefor, ofpartition walls positioned vertically in said crank case dividing saidcrank ease into a number oit independent units, a second partition wallextending horizontally and dividing each unit of said crank case into anupper and lower compartment,a number of oil Ydistributing devicespositioned on the upper` face of said horizontal wall, andintercommunicating passages through said vertical and horizontalpartition walls leading from the upper chamber et one unit to the lowerchamber of the adjacent unit, substantially as specified.

In witness whereof, I have signed this 'specification in the presence oftwo subscribing witnesses.
